Try https://www.pandasecurity.com/en/ . It provides free service which is sufficient I think.

Download ESET SysRescue which is a free tool to make sure you have no malware and in case you do this will fix it
https://download.eset.com/com/eset/tools/recovery/rescue_cd/latest/eset_sysrescue_live_enu.iso
Filename: eset_sysrescue_live_enu.iso | File size: 736 MB | Version: 1.0.20.0
and use Rufus to make a bootable USB
https://github.com/pbatard/rufus/releases/download/v3.14/rufus-3.14.exe
Filename: rufus-3.14.exe | File size: 1.1 MB | Version: 3.14
and this is a tutorial of doing the whole process
